昨天我尝试设置 Graylog。我还安装了 Java、Mongodb 和 Elasticsearch。无法正常运行，因此我决定删除它们并重新开始。我使用此处的说明卸载 Java8：如何彻底卸载Java？。但是，当我尝试再次安装它时，它给出了一个错误：

Oracle JDK 8 is NOT installed.
dpkg: error processing package oracle-java8-installer (--configure):
subprocess installed post-installation script returned error exit status 1
E: Sub-process /usr/bin/dpkg returned an error code (1)
删除所有配置文件和其他 Java 文件也无济于事。在 Java Yes/No GUI 之后，它一直显示相同的错误。
我还注意到它等待了相当长一段时间
Processing triggers for shared-mime-info (1.5-2ubuntu0.1) ...
然后再继续。另外，我之前尝试安装/升级软件包，但它一直显示与上面提到的相同的错误输出。
举个例子
apt-get install --reinstall shared-mime-info
这是一个冗长且毫无用处的背景故事，但我不知道该怎么做了。我今天花了几个小时使用 Google 并试图找出问题所在，但这对我没有任何帮助。
谢谢你！
答案1
这个答案不会让你高兴，但据我记得，14.04 和 Java 8 不能一起工作。这些是我最初的安装说明：
::Need Latest Java?;;
You're screwed...
Try:
apt-get install openjdk-8-jre
If it fails, then
apt-get install openjdk-7-jre
Ref:

另请参阅相关/重复错误的最后一条评论：
https://bugs.launchpad.net/trusty-backports/+bug/1368094

还有其他一些可供探索的选项：
如果您想要 Oracle Java，那么很可能您需要手动找到 tarball/.dev/.xxx 文件并直接下载它，而不是依赖 Oracle 安装程序包。
看起来“管理权从 Oracle 转移到了 Red Hat”，因此看看你是否可以在 Red Hat 上挖掘它。
最好的！
